When a man threatened to harm himself at Rockefeller Plaza, security crews and police quickly responded, but not before the man cut his own wrist with a knife.

Matt Lauer addressed the incident on-air, as the anchors had originally planned a segment outdoors.

"A short time ago a man out there tried to harm himself with a knife, he did manage to cut himself, he was controlled by our security team out there," Lauer said on Today. "However he did harm himself in some way, he's now being attended to."

Al Roker also addressed the incident on Twitter, writing, "We had a disturbing incident by our window this am. It is still difficult and some choose to make light of it or use it as a joke. Not funny."

According to the Daily News, the man was ranting about the corruption of the Internal Revenue Service, saying that the agency "ruined his life."

The man was taken into medical care and is expected to survive.

NBC News later issued a statement: "This morning shortly before 8 a.m., a man attempted to harm himself on Rockefeller Plaza outside the Today show studio. He was quickly subdued by security officers on site and taken to an area hospital for treatment. We have strict security protocols in place to protect visitors to the Today show and those procedures were followed and effective. We are very grateful for the actions of our security team and the NYPD that no others visiting the show were harmed in the incident."

All secure on the plaza after a scary incident. Thanks to our security team and the NYPD.
